8.4.2.2 Site Specific Survey 38.


In order to provide more specific information in relation to the East Anglia THREE site, additional data was collected along the offshore cable corridor, with further sampling also undertaken within the East Anglia THREE site. The survey was undertaken in 2013 (reported in Fugro EMU 2013) and can be found in Appendix 10.4.

The survey plan included sub-sampling of sea bed sediments for subsequent analysis of contaminants from 15 sampling sites within the offshore cable corridor and the East Anglia THREE site. During the survey, a 0.1m2 stainless-steel Day grab was used to collect sea bed samples for analysis. Samples were submitted to a specialist UKAS accredited chemistry laboratory for the analysis of the following contaminants:
